WIRE-STAY-MAKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 638,538, dated December5, 1899.

Application filed June 29,1899- Serial No. 722,238. (No model.)

To all whom it may concern:

Beit known that I, GEORGE W. WILLIAMS, a citizen of the United States,residing at Humansville, in the county of Polk and State of Missouri,have invented a new and useful Wire-Stay-Making Machine, of which thefol lowing is a specification.

My invention relates to wire-stay-making machines, and has for itsobject to provide a simple and efficient construction and arrangement ofparts whereby a wire stay may be crimped or formed preparatory to itsapplication to the runners ofa wire fence, said stay being oflooped-wire construction and being provided at intervals correspondingwith those between the runners of the proposed fence with means forengaging said runners.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims, it being understoodthat the improvement is susceptible of various changes in the form,proportion, size, and minor details of construction without departingfrom the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a stay-benchconstructed in accordance with my invention. Fig. 2 is a plan view ofthe same, showing the completed stay in place thereon. Figs. 3 and t aredetail views of portions of stays constructed upon the improved bench.Fig. 5 is a detail View of a portion of the apparatus, showing atwisting-lever engaged with one of the intermediate eyes of the stay inthe course of constructing the same.

Similar reference characters indicate corresponding parts in all thefigures of the drawings.

The apparatus embodying my invention includes a bench having a frameconsisting of side beams 1 and head and foot end beams 2 and 3, togetherwith suitable supports or legs 4. Connecting the side beams aretransverse rest-bars 5, each of which is provided with a plurality offixed forming-pins or main-stayforming elements 6, arranged in relativepositions to suit the formation of the stay which is to be constructedthereon, and pivotally mounted at oneend upon the head end bar 2 is alever 7, carrying a plurality of movable forming-pins orauxiliary-stay-forming elements 6, which are located in the intervalsbetween the transverserest-bars 5; also, the foot end bar 3 carries pins6 for forming the lower end of the stay, and near its outer side theupper surface of said foot end bar is slightly channeled or cut away toform a seat 8, spanned by a movable clamp or button 9, pivoted to theend bar and adapted to be turned to one side to allow the insertion orremoval of the extremities of the blank from which the stay is formed;also, the free end of the lever or movable-pin-support 7 is constructedto form a grip 10, and when the lever is elevated it fits in a notch 11in the lower edge of the foot end bar, where it is adapted -to be heldby a lock 12, consisting of a pivotal button; also, at an intermediatepoint upon one of the side bars, preferably that which is remote fromthe operator when the machine is in use, is a wire clamp or holder 13,which in the construction illustrated consists of a block or striphaving one end reduced to form a wire seat 14.

In operation a wire-blank of the proper length for forming a stay isengaged at its center with the head-pin 6 and afterengaging one arm ofthe blank or one side of the loop thereof in the clamp 13, as indicatedin dotted lines in Fig. 1, the other arm or side thereof is formedaround the pins 6 and 6, as indicated in dotted lines in said figure,the extremity thereof being engaged by the clamp 9. Subsequently theother arm or side of the blank is disengaged from the clamp 13 and iscorrespondingly formed around the pins, and its extremity in turn isengaged with the clamp 9. Having reached this point in the formation ofthe stay, the movable pin-support 7 is released by turning the button 12to the dotted position indicated in Fig. 1, and the said support islowered, as indicated in Fig. 5, to withdraw the movable pins 6 from thecentral eyes of the wire-blank, and a twisting-lever 15 is engaged withsaid eyes and is turned in a plane between two adj acent transverserests 5 to twist the adjacent portions of the sides or arms of theblanks between the adjacent fixed pins 6 to provide theoppositely-twisted portions 16, as shown in Fig. 2.

Displacement of the sides or arms of the stayblank during this twistingoperation, which is performed for each eye of the blank, is prevented bythe frictional contact of the staywire with the pins and also,terminally, by the engagement of the clamp 9 with the extremities of.the blank. Having completed the twisting operation, the stay may bedisengaged by turning the clamp 9 to the dotted position shown in Fig.2.

From the above description it will be seen that the construction issimple and that by Varying the relative positions of the fixedforming-pins stays of difierent configurations may be formed thereon.For instance, in the drawings I have illustrated auxiliary forming-pins6, arranged upon that transverse rest-bar which is adjacent to the headend bar 2 of the frame, and by employing these pins instead of theadjacent side pins, which are arranged upon obliquely-disposed lines, astay having a head end, as shown in Fig. 4, may be formed. These lateralpins 6 Fig. 2, form side loops 17, which are adapted in practice to becoiled around the fence-stays 18 (indicated in dotted lines in Fig. 3)to fasten the stay to the runners; but when a stay having a smooth upperend (or one wherein there is no upward projection beyond the uppermostrunner of the fence) is to be constructed the auxiliary pins 6 areemployed to provide the configuration shown in Fig. 4 at 19, thisportion 19 being adapted to be coiled around the uppermost runner tofasten the top of the stay. It will be understood, however, that I donot desire to be limited to any specific relative arrangement of theforming-pins, as they may be varied to provide for the construction ofstays which differ widely in configuration without departing from thespirit of my invention.

An important feature of the construction resides in the fact that afterthe sides or arms of the blank have been engaged with the forming-pin,the subsequent twisting of the intermediate portions, which primarilyare engaged with the movable forming-pins 6,draws the portions of theblank between said twists with a tension which insures the formation ofregular geometrical figures, and the parts of the stay retain thesepositions after removal from the bench.

Having described my invention, what I claim. is-

1. A stay-forming bench having fixed formingpins around which a staywire may be formed, and movable forming-pins arranged at intervals, andalso adapted for engagement by the stay-Wire, and capable of withdrawalfrom such engagement to release the stay, substantially as specified.

2. A stay-forming bench having spaced rests and fixed forming-pinscarried thereby,

and intermediate forming pins movably arranged in the intervals betweensaid restbars, substantially as specified.

3. A stay-forming bench having spaced rest-bars carrying stationaryformingpins, and a movable support provided with movable forming-pinsarranged in the intervals between said restbars, substantially asspecified.

4. A stay-forming bench having spaced pincarrying rest-bars, apivotalsupport mounted for swinging movement toward and from the planeof the rest-bars, and carrying movable forming-pins for arrangement inthe intervals between said rest-bars, and means for securing saidmovable pin-support in its operative position, substantially asspecified.

5. A stay-forming bench having a frame, transverse spaced rest-bars,stationary form ing-pins carried by said bars, a lever pivotally mountedat one end to the frame, movable forming-pins carried by said lever andarranged in the intervals between said rest-bars, and a lock forsecuring the lever in its operative position, substantially asspecified.

6. A stay-forming bench having a frame, transverse spaced rest-bars,stationary forming-pins carried by said rest-bars, a movable pin-supportmounted for adjustment toward and from the plane of the rest-bars andprovided with forming-pins for arrangement in the intervals between therest-bars, means for holding said movable pin-support in its operativeposition, and a wire-clamp carried by the frame for holding one side ofthe blank during the engagement of the other side with the forming-pins,substantially as specified.

7. A stay-forming bench having a frame, transverse spaced pin-supportingrest-bars, a movable pin-support having forming-pins ar-. ranged in theintervals between said rest-bars, means for holding said pin-support inits operative position, and a terminal blank-engaging clamp mounted uponthe frame adjacent to one end for engaging the extremities of thestay-blank, substantially as specified.

8. A stay-forming bench having fixed mainstay-forming elements, aroundwhich a staywire may be formed, and movable auxiliarystay-formingelements also adapted for engagement by the staywire, and capable ofwithdrawal from operative relation with the main-stay-forming elementsto release a completed stay, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
